A visitor of program elements based on their
kind with default behavior appropriate for the
RELEASE_6
source version. For
elements XYZ that may have more than one
kind, the
visitXYZ methods in this class delegate
to the
visitXYZKind method corresponding to the
first argument's kind. The
visitXYZKind methods
call
defaultAction
, passing their arguments
to
defaultAction
's corresponding parameters.
Methods in this class may be overridden subject to their
general contract. Note that annotating methods in concrete
subclasses with @Override
will help
ensure that methods are overridden as intended.
WARNING: The ElementVisitor
interface
implemented by this class may have methods added to it or the
ElementKind
enum
used in this case may have
constants added to it in the future to accommodate new, currently
unknown, language structures added to future versions of the
Java™ programming language. Therefore, methods whose names
begin with "visit"
may be added to this class in the
future; to avoid incompatibilities, classes which extend this class
should not declare any instance methods with names beginning with
"visit"
.
When such a new visit method is added, the default
implementation in this class will be to call the visitUnknown
method. A new abstract element kind
visitor class will also be introduced to correspond to the new
language level; this visitor will have different default behavior
for the visit method in question. When the new visitor is
introduced, all or portions of this visitor may be deprecated.
